Repaint() in java3d?

Question

Hey, is there a methods in java3d who works like repaint() and paintComponent() methods?
I have to draw something after click the button (points in 3D) and i have to repaint screen (first i have only axis on screen). How should I do this?
this is method panel3d where I draw an axis
    JPanel panel3d() {
        JPanel panel = new JPanel();
        panel.setLayout(new BorderLayout());
        GraphicsConfiguration config = SimpleUniverse.getPreferredConfiguration();
        Canvas3D canvas = new Canvas3D(config);
        panel.add(canvas);
        universe = new SimpleUniverse(canvas);
        root = new BranchGroup();
        axis();
        universe.addBranchGraph(root);
        universe.getViewingPlatform().setNominalViewingTransform();
        return panel;
    } axis method:
public void axis() {
        Shape3D shape = new Shape3D();
        TransformGroup objTrans = new TransformGroup();
        objTrans.addChild(shape);
            IndexedLineArray axisLines = new IndexedLineArray(18, GeometryArray.COORDINATES | LineArray.COLOR_3, 30);
            axisLines.setCoordinate( 0, new Point3f(-0.3f/10, 0.0f/10, 0.0f/10));
        shape.setGeometry(axisLines);
        root.addChild(objTrans);
}and I want to draw after click that what I have in method showGraph:
public void showGraph() {
        Shape3D shape = new Shape3D();
     PointArray point = new PointArray(2,GeometryArray.COORDINATES);
//for example one point          
        point.setCoordinate(0, new Point3f(1.0f/10, 1.0f/10, 1.0f/10));
        shape.setGeometry(point);
        root.addChild(shape);
    }and the problem is that I don't know how to draw it after clicking. If I add this method to panel3d method then it will be draw at start of this program
I hope that you understand me :)
Thanks in advance for help!
